The first and most critical
step in the facility evaluation process is the field-testing and
on-site observations and interviews. Our technical experts
conduct a comprehensive evaluation of the facility to identify opportunities
for enhancement. The focus is to identify opportunities that will
reduce O&M costs, reduce fuel consumption, identify and reduce gas losses, increase throughput, and add
revenues for the facility. This process follows ACTT/Health's proprietary optimization checklist.
A few of the key tasks identified in that checklist include:
- Conducting
in-depth interviews with local operating, repair personnel, equipment analysts, and supervisors
to discuss known and potential problems and enhancement opportunities.
- Reviewing maintenance and performance monitoring
systems and records.
- Obtaining
empirical equipment performance data to help quantify enhancement
opportunities and establish baseline performance.
Specific tests includes:
-
Measuring compressor efficiency study at several ratios of compression (if possible)
-
Conducting a basic pressure drop study of yard piping and conditioning equipment (coolers, heaters, dehys, etc.)
Conduct an Infrared(IR)
Thermography study to identify areas of energy loss.
Evaluating compressor loading matrix and
compressor sizing to determine appropriateness at typical operating pressures.
Screening for natural gas leaks from pressurized and venting components.
Measuring and tagging identified leaks (as accessible depending on station operation) to include:
- Unit valves on blown down compressors
- Blow down valves on pressurized compressors
- Rod packings on pressurized reciprocating compressors
- Seal vents on centrifugal compressors
- Pressure relief valves
- Power gas vents for compressor unloaders
Performing a baseline turbocharger performance study (optional).
